Graham, Scott: It's over if Mitt wins S.C.

“If for some reason, he’s not derailed here and Mitt Romney wins South Carolina, … I think it should be over,” Sen. Lindsey Graham (R-S.C.) said Sunday on NBC's “Meet the Press.” “I hope the party would rally around him if he did in fact win South Carolina.”

“If Romney wins South Carolina, I think the game’s over,” added Rep. Tim Scott (R-S.C.), a freshman member of House Republican leadership. “I think this is the last stand for many candidates.”

The former Massachusetts governor is leading in the polls in South Carolina in advance of Saturday's primary.

Either Graham or Scott would be a coveted backer for any presidential candidate, but both lawmakers said Sunday that they don’t know which candidate they would endorse.

“I don’t even know who I’m going to vote for because I know what happens in South Carolina, we pick presidents here and this is the best chance I’ve seen in years for the Republican Party to revive itself,” Graham said.
